Over at MWC 2016, Imagination has been busy showing off its real-time ray tracing trickery running on the firm’s quad-cluster PowerVR GR6500 GPU, a chip small enough to fit into mobile devices.
What’s so great about ray tracing? Normally, when programming a game, the graphics have to be done and then realistic lighting effects such as reflections and shadows (and other visual effects such as transparency) have to be added on top in an often very lengthy process.
Ray tracing, however, boils this process down and simplifies things to make it a far less stressful endeavour. Imagination told us: “What you do is you define properties for the materials. You shoot some rays and the computer creates the reflections for you. Instead of having to program shadows and reflections, you just have to use ray tracing to do that.”
As you might guess, however, this is demanding on graphics hardware, but Imagination’s new PowerVR GR6500 with its Wizard ray tracing tech is set to deliver such nifty visuals to smartphones and tablets, as it’s small enough to fit in these mobile devices. (Although it’s also highly scalable, and thus aimed at the likes of laptops and games consoles as well, if …read more
